NPT threads must be sealed using a high quality PTFE tape and/or
PTFE paste product. Refer to thread sealant manufacturer’s instructions
on how to apply thread sealant.

Sealing performance may vary based on many factors such as pressure,
temperature, media, thread quality, thread material, proper thread
engagement and proper use of thread sealant.

Customer should limit the number of times an NPT fitting is assembled
and disassembled because thread deformation during assembly will
result in deteriorating seal quality over time. When using only PTFE tape,
consider using thread lubrication to prevent galling of mating parts.
